JACKET FOR CYLINDERS.

Specification of Letters Patent.

Patented Oct. 20, 1908.

To all whom it may concern:

Be it known that we, GEORGE B. PIoKoP and JosnPH W. MrLLs, citizens of the United States, and residents of New Britain, in the county of Hartford and State of Connectiout, have invented a new and Improved Jacket for Cylinders, of which the following is a specification.

Our invention relates to the class of devices specified and the object of the invention is to provide a device of this class having special features of advantage and utility.

A device in the use of which these objects may be attained is illustrated in the accompanying drawings in which Figure 1 is a top or plan view of a water jacket embodying my invention with parts broken away to show construction, the cylinders being omitted. Fig. 2 is a view in side elevation of a set of cylinders equipped with my improved jacket, the latter being partially cut away to show construction.

In the accompanying drawings the numeral 5 indicates a base that may be ofany usual form and construction, that herein shown being of the kind usually employed in the construction of motor vehicles to support the engine.

The numeral 6 indicates cylinders mounted upon and properly secured to the base, these cylinders being of any usual form and construction common to motor vehicles, or other mechanism embodying gas or explosive engines.

It will be understood that the mechanism may consist of any desired number of cylinders equipped with the usual devices or parts employed in the operation of the motor, but as these form no part of the present invention detailed illustration and description are omitted herein as not being required for a thorough and complete understanding of the invention. There are, however, shown in connection with the cylinders the stems 7 of exhaust valves, springs 8 for closing the valves, and exhaust pipes 9 communicating with the exhaust openings 10 from the cylinders. The outer surfaces of the cylinders are turned concentric with the bore so that an even thickness of the walls of the cylinders is insured. In this turning operation a shoulder 11 is preferably formed upon each, upon which a jacket may rest or against which it is secured.

The jacket for several cylinders is formed as a unit, thus roviding a free and uninterrupted circulation of water from end to end of the jacket, thereby maintaining an even temperature throughout. l/Vhile there are shown herein two inlet and outlet pipes each, a single inlet and a single outlet only may be employed with satisfactory results. This jacket is formed in halves separated preferably on a plane extending lengthwise of the cylinders and on a line diametrically thereof. The jacket halves 12 may be formed du licates each of the other, and each is provi ed with a top wall 13, a bottom wall 14, an outer wall 15 and an inner or facing wall 16. Each jacket half is provided with a set of semicircular recesses 17 formed in the inner wall 16.

When the halves are secured together circular holes or openings are formed thereby for the reception of the cylinder 6. A jacket half thus constructed has a water chamber 18, the water chambers in'two companion halves communicating each with the other by means of ports 19 through the facing walls 16 of the halves. A web 20, projecting preferably from the outer Wall, extends lengthwise of the chambers forming astrengthening element. Stay bolts 21 or other convenient devices are employed for holding the jacket halves together, the bolts, when used, preferably extending through the ports 19. It will be seen that the jacket halves thus constructed each in itself forms a com lete water chamber. The meeting walls an the semicircular recesses may be readily finished to accurately it together, and also accurately fit the cylinders. It has been found by experiment that the halves may be so nicely fitted together that but the application of shellac to the meeting faces w1 effectually prevent the esca e, of water, 9

and this application of shellac will not be reuired in all instances. The halves being 0 amped together on the several cylinders, thus forming a com lete jacket, the cylinders are tied together t ereby greatly stiffening the motor. All of the Walls of the jacket are contained complete in the halves, so that there is no contact of the contents of the jackets with the cylinder, thereby avoiding the element of rust of the cylinders from this cause, thus materially increasing the life thereof. In the event of the water freezing in the jacket, or the latter becoming injured from any other cause, a new jacket may be readily placed as a substitute and at a cost guickly andslight as compared with that of a new set of cylinders, as in cases where the cylinders form a part of the walls of the jacket.

While there has been shown herein a jacket in which there is contained a water chamber with the walls complete in the jacket, two halves of the jacket being applied to the cylinder from opposite sides thereof, we do not limit ourselves to this sectional construction of the jacket or to the application of sections from opposite sides, as any structure in which there is a water jacket with the chamber therein completely formed by the walls of the jacket will come within the scope and intent of the invention.

1. A jacket for cylinders composed of half sections, each having a chamber with inclosing walls complete therein and with the outer face of its wall having a recess for the reception of a portion of a cylinder.

2. A jacket for cylinders composed of half sections, each having a chamber with inclosing 'walls complete therein and with the outer face of its wall having a recess for the reception of a portion of a cylinder, the dividing line between the sections being on a plane passing lengthwise through the recess formed by the joined half sections.

3. A jacket for cylinders composed of half sections duplicates each of the other, each half having a chamber with inclosing walls complete therein and with the outer face of its wall having a recess for the reception of a portion of a cylinder.

4. A jacket for cylinders composed of half sections, each section having a chamber with inclosing walls complete therein and one wall of which is formed to fit the wall of an opposite section, said wall having a recess to fit and receive a portion of a cylinder, and

means for securing the halves together.

5. A jacket for cylinders composed of half sections, each having a chamber one wall of which is formed to fit the wall upon the opposite section, said wall also having a recess for the reception of a portion of a cylinder, communicating ports between the chambers in the half sections, and means for securing the sections together.

6. A jacket for cylinders composed of half sections, each having a chamber with Walls complete, one wall of each chamber being arranged to fit the wall of the chamber on the opposite section, said meeting walls having outside the chamber recesses for the reception of a portion of a number of cylinders, communicating ports between the chambers in the sections, and means for securing the sections together.

7. A jacket for cylinders composed of half sections, each having a chamber with walls complete, the meeting walls of each section having a series of recesses adapted to receive a portion of a cylinder, and with communicating ports located between the cylinder recesses, and means for joining the sections together.

8. A jacket for cylinders composed of half sections, each having a chamber with walls complete, and with a series of semicircular recesses formed upon the outer face of the meeting walls of each section, communicating ports between the sections and located between the cylinder recesses, and means for securing the sections together.

9. A jacket for cylinders composed of two half sections duplicates each of the other, each having a chamber with walls complete, the outer face of the meeting walls of each section having a number of semicircular recesses for the reception of cylinders, communicating ports between the chambers and located between the semicircular recesses, and means for securing the sections together.

10. A jacket for cylinders composed of two half sections each having a chamber with walls complete, the meeting walls of the sections being adapted to fit each other and each having a recess for the reception of a portion of a cylinder, a web extending from the outer wall of the chamber to the wall forming the cylinder recess, and means for joining the sections together.

11. A cylinder jacket having a water chamber the inclosing walls of which are complete within the jacket, said jacket being arranged to fit a cylinder.
